Bloody hell, this guy won't give up!

The year is 1942, my boat is a 7C

A few hours ago my watch crew spotted an enemy destroyer far off in the distance. I checked it out and decided to dive for safetys sake. I dove to approximately 45 meters and sailed at roughly 4 knots. Maybe 10 minutes later this destroyer is on top of me and starts dropping depth charges! I have turned my boat in all kinds of directions and have attempted to out smart him for roughly 2 1/2 hours now. I have stayed at silent speed with a mix of flank during depth charges. I am now sitting at 255 meters and she is holding strong.

This has been some of the most fun I have had in SHIII, but also very frustrating. He has not used ASDIC since he first began his attack run. I can't lose him.

What can I do? Why did he stop using ASDIC? I haven't heard any pings for quite some time.

This was one destroyer, my god what will happen when I attack a convoy fully escorted? This is my first time playing GWX late in the war. (I usually only last until about 41)

Also, this is for a patrol with my wolves at war character. This really makes things SO much more intese. I have spent hours writing a story for my character and his crew and doing training patrols etc... I can't lose him damnit!

(Edit: Just as I am writing this, I notice the destroyer is now at medium range! I may have finally lost him....)
(Edit again: Nope... this damn guy is coming back now.)
